A finite-element program, ANSYS, was used to determine the change in physical dimensions of oilfield tubulars and the growth of stresses in their walls as these tubulars were run and landed into a drillhole. Ovalities and axial and tangential stresses modeled with a finite-element method (FEM) are presented in easy-to-use charts for 7- acid 9 5/8-in.-OD API casing. Axial bending stresses with the FEM are are compared with those under Lubinski's bending equation and the classic beam-bending equation.

Characterization of tight-gas sand reservoirs from horizontal-well performance data using an inverse neural network Kulga, B.; Artun, E.; Ertekin, T. (Elsevier BV, 2018-11-01) Characterization of a tight-gas sand formation using data from horizontal wells at isolated locations is challenging due to the inherent heterogeneity and very low permeability characteristics of this class of resources. Furthermore, characterizing the uncontrollable hydraulic-fracture properties along the horizontal wellbore requires financially demanding and time-consuming operations. In this study, a reservoir characterization model for tight-gas sand reservoirs is developed and tested. The model describ...
Integrated deterministic approaches for productivity index of reservoirs depleted by horizontal wells and undergone multiphase flow conditions Al-Rbeawi, Salam (Elsevier BV, 2019-04-01) This paper introduces new integrated approaches for estimating pseudo-steady state productivity index (PI) and shape factor of oil and gas reservoirs drained by horizontal wells and dominated by multiphase flow conditions. These approaches couple PVT data, relative permeability curves, and pressure distribution models during pseudo-steady state flow (PSS). The objective is eliminating the uncertainties of applying single phase flow models and substantially comprising the realistic parameters that govern mul...
Investigation of combustion process through horizontal wells Bağcı, Ali Suat (Informa UK Limited, 2005-04-15) Dry combustion was accomplished with the application of different horizontal well configurations in a 3-D model using high gravity oil. Seven experiments using Raman crude oil (18 degrees API) were carried out in the laboratory with a 40 cm square 3-D model having a thickness of 15 cm. Five different well configurations were applied to recover Raman crude oil. The model was packed by tamping a mixture of crushed limestone, water and crude oil. A total of 36 thermocouples were used at the top, center and bot...
Damage Progression in Thick Curved Composite Laminates under Static and Fatigue Loading Tasdemir, B.; Çöker, Demirkan (IOP Publishing; 2018-06-22) In this study, damage behavior of curved carbon fiber reinforced polymer (CFRP) composite laminates that are important sub-structures (ribs, shear webs and spar flanges etc.) for wind turbine blades are investigated under static and fatigue loading conditions. Cross-ply curved specimen consisting of groups of three 0 degrees and 90 degrees layers is used for clear observation of the matrix cracking in thicker plies. Damage mechanisms and locations under static and fatigue loadings are examined. In the exper...
Mechanical fatique and life estimation analysis of printed circuit board components Genç, Cem; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2006) In this thesis, vibration induced fatigue life analysis of axial leaded Tantalum & Aluminum capacitors, PDIP and SM capacitors mounted on the printed circuit boards are performed. This approach requires the finite element model, material properties and dynamic characteristics of the PCB. The young modulus of the PCB material is obtained from 3 point bending tests, resonance frequencies are obtained from modal tests and transmissibility’s of the PCB are obtained from transmissibility tests which are used as ...
